How to modify a Jelastic installation when wrapping a jps manifest in my own manifest? - nginx

Question

The Jelastic Marketplace is full of interesting software. However, sometimes, they do not comply to my security needs. In those cases, I would like to write my own manifest that would install the manifest from the marketplace and add up the components that I need for my use-case. Let's take an example: I would like to wrap the kubernetes installation with the addition of a load-balancer. I would like to do something like this:
type: install
name: My Example Manifest
onInstall:
- install:
jps: https://github.com/jelastic-jps/kubernetes/blob/1.23.6/manifest.jps
envName: env-${fn.random}
settings:
deploy: cmd
cmd: echo "do nothing"
topo: 0-dev
dashboard: general
ingress-controller: Nginx
storage: true
api: true
monitoring: true
version: 1.23.6
jaeger: false
- addNodes:
- nodeType: nginx-dockerized
nodeGroup: bl
count: 1
fixedCloudlets: 1
flexibleCloudlets: 4
The issue I am having here is that the manifest cannot add the nodes, because of the following error:
user [xyz] doesn't have any access rights to app [dashboard]
What am I doing wrong? How can I make this manifest work? I tried to set user: root in the addNodes function but it doesn't help.
Of course, I am interested in suggestions involving one single install manifest. I know I could make it happen by first installing the kubernetes manifest and then running an update manifest that would add my load-balancer nodes. I would like, however, to package the whole thing within one single step, as described by my manifest above.
